Hi Donald,
After Effects is the easy answer.
Boris is mostly recognized for their plug-ins. I did find Boris Blue which is a stand alone program, but it doesn’t come close to the functionality of AE. It also looks like it only runs on a PC (don’t know if you are using a Mac).
If you have a Mac, you may want to compare After Effects to Apple’s Final Cut Studio Pro. Studio Pro has several applications included in the bundle. Their motion graphics application is called Motion. Again, I think After Effects is the better of these two, but you really do get a nice suite with Studio Pro.
Definitely check out the system requirements of both these applications before your purchase. I would also recommend downloading trial version of After Effects (unfortunately Studio Pro doesn’t have a trial version as far as I know).
So… while I’m a huge fan of After Effects, you may get more bang for your buck with all of the applications included in Final Cut Studio Pro. You do need a Mac to run Studio Pro though.
Hope this helps a little.
Bob
